SPECIFICAIIQN forming part of Letters Patent No. 523,869, dated July 31,1894.

Application filed April 4, 1894.

Yonkers, in the county of Westchester and State of New York, have invented certainV new and useful Improvements in Pile-Wires.

for Looms, of which the following is a speciication.

This invention relates to certain improvements in pile-wires for looms, for which Letters Patent Were granted to me heretofore, No.l 500,275, dated June 27, 1893, and No. 512,063, dated January 2, 1894; the improve-4 ments being designed with the view ofsimplifying the connection of the holder with the cutting-blade and of dispensing with any locking-spring for the blade, so that the holder and blade can be readily attached to new and old pile-wires.

The invention consists of a pile-wire for looms, in which la sheet metal holder is attachedv to the end of the pile-wire, said holder being bent over at its upper and lower edges, so as to form a dovetailed socket for the shank of the cutting-blade, which shank is soldered to the holder flush with the pile-wire, as will be fully described hereinafter and iinally .pointed out in the claims.

In the accompanying drawings,-Figure 1 represents a side-elevation of my improved pile-wire for looms. Fig. 2 is a top-view of Fig. 1. Fig. 3 is a rear-elevation of the pilewire, and Figs. 4 and 5 are vertical transverse sections, on lines 4, 4, and 5, 5, Fig. 1, drawn on a larger scale.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a pile-wire for looms, B a Ablade-supporting holder, which is made of suitable sheet metal and preferably of sheetsteel and C the cutting-blade. The holder B- is made from a suitable blank, which is bent up at its upper and lower edges so as to form top and bottom iangesl for the elongated shank d of the cutting-blade C. By bending up the holder at its upper and lower edges, a dovetailed socket is formed by which the holder can b e readily attached at one end to the end a of the pilewire, which for this purpose is. correspondin gly recessed at iits upper and lower edges so as to be readily inserted into the holder and Serial No. 506,281. (No model.)

be then Iirmly attached thereto by brazing or l rigid and firm connection between the holder and blade is obtained. The shank d ofthe blade yC is also made of dovetailed cross-'secf tion, so as to lit accurately into the holder B. The outer end of the blade Bis bent at asuitable angle of inclination to the body of ythe blade, so as to form a guard d for the blade and produce the ready glancing off of the blade. from the reeds, in case it'should strike against the same. The shank of the blade C is provided with a slightprojection or shoulder d2 at its upper edge, immediatelyadjacent to the end of the holder, which serves as a stop for the blade when inserting the shank into the holder. The edge of the shoulder d? remains blunt for a short distance, say three eighths of an inch, so as not to injure the holderwhen the edge of the blade is ground on the stone.

The edge of the blade C is slanting or curved in upward direction from the end of the blunt shoulder d2 and sharpened, the remaining upper 'portion of the blade, the edges -of the guard d andthe bottom edge of the blade remaining blunt. The blade C cuts therefore only at the upwardly-curved part when it. is movedacross the pile from one side of the loom to the other. When the blade becomes dull, it is sharpened again without being removed from the holder and when the blade is entirely worn out, it is removed from the holder and a new blade inserted into the same. The holder vand blade can be applied to old pile-wires in which the blade is worn out, by cutting the same olf and attaching the holder and its lblade to the end of the pile-wire.v

Having thus described my invention, I claim as new and desire to secure by Letters Patentt A 1. The combination, with' a pile-wire the end of which is recessed at its upper and lower edges, of a sheet-metal holder attached to the recessed end of the pile-wire, said holder being bent-up at its upper and lower edges so as to form a dovetailed socket eX- roe cuttingfblade having an elongated dove-tailed shank secured in the socket of the holder,

substantially as set forth.

2. The combination, with a pile-wire, of a holder attached at one end of said pile-Wire, said holder being bent-up at its upper and lower edges so as toform a dove-tailed socket extending along one side of the holder and a cutting blade having an elongated dove-tailed shank secured in said socket, and a shoulder on one edge, against Which the end of the holder abuts, substantially as set forth.

3. The combination, with a pile-Wire, the end of which is recessed at its upper and lower edges and is dovetailed in crosssection, 0f a sheet-metal holder attached to said re- In testimony that I claim the foregoing as `my invention I have signed my name in presence of tWo subscribing witnesses.
